extraction of zinc | application of zinc refining process

extraction of zinc | application of zinc refining process

The best concentration method for zinc ore is known as froth flotation. Concentration of Ore: Froth Flotation Process. Froth Flotation process is mainly used to remove gangue from sulphide ores. The ore is powdered and a suspension is created in water. The main ingredients of the froth flotation are the Collectors and Froth Stabilizers. Collectors (pine oils, fatty acids etc) increase the wettability of the …

why only sulphide ore is concentrated by froth flotation

why only sulphide ore is concentrated by froth flotation

The ore was concentrated into PbS-ZnS as concentrate and feldspar as tailing by froth flotation using the Denver D.12The kinetic theory explains why there was decrease in the Zn dissolution at increasing 1 …

lead zinc separation by flotation - froth flotation

lead zinc separation by flotation - froth flotation

Some of the metals that can do the job are copper and lead. At a pH between 8-9 lead can activate sphalerite to cause it flotation. So the reason is during the flotation of the two there may be lead re dissolution from galena which may activate sphalerite to cause it flotation. It may best if you are doing bulk flotation of the two

zinc: smelting, producing and classification-metalpedia

zinc: smelting, producing and classification-metalpedia

Rarely is the ore, as mined, rich enough to be used directly by smelters; it needs to be concentrated. Zinc ores contain 5-15% zinc. To concentrate the ore, it is first crushed and then ground to enable optimal separation from the other minerals. Typically, a zinc concentrate contains about 55% of zinc with some copper, lead and iron. Zinc concentration is usually done at the mine site to keep transport costs to …
